The PNZ155 (PN155) is a silicon NPN phototransistor with a peak sensitivity wavelength of 800nm. It has a high photosensitivity of 0.05mA at 100lx and a fast response time of 4µs at 10V.
The PNZ155 is a flat‑type plastic package silicon NPN phototransistor designed for optical control systems. It offers high sensitivity, wide spectral response suited to GaAs LEDs, and low dark current.
Key specifications include a collector‑to‑emitter voltage of 20 V, a maximum collector current of 10 mA, and a peak sensitivity at 800 nm with a 70° acceptance half‑angle. The device operates from –25 °C to +85 °C and is covered by standard export and liability notices.
